Hokkaido is Japan’s largest prefecture, stretching about 400 kilometers from north to south, roughly the size of Taiwan. Because of its vast scale, weather conditions vary noticeably by location, even among popular destinations like Sapporo and Asahikawa. Central and southern areas tend to be slightly milder, while eastern Hokkaido is generally colder.

From March to May, Hokkaido remains much cooler than Japan’s main island. March in particular can feel almost like winter, making warm, winter-grade clothing essential. If your itinerary covers multiple areas or several days, packing extra layers is a smart move.

Below, we have compiled spring weather data for two of Hokkaido’s main tourist hubs, Sapporo and Asahikawa, to use as a practical reference when planning your trip.

According to the Japan Meteorological Agency, average temperatures in March still hover near freezing, and snow often remains on the ground in both cities. This period is also the last chance of the season to experience Hokkaido’s famous powder snow. From April onward, temperatures rise gradually, though daily swings of around 10°C (18°F) are still common.

For full days of sightseeing, dressing in layers is highly recommended, along with handy items like disposable heat packs. Bringing regular medication is also advised, as sharp temperature changes can sometimes cause discomfort. If renting a car, confirm winter equipment such as snow tires in advance, and allow extra time in your schedule in case weather affects transportation.

As mentioned earlier, Hokkaido’s vast size means weather conditions vary slightly by area. Even so, March still feels very much like winter across the region, with heavy snow remaining in many places. This also marks the final window of the season for skiing.

If you want to experience Hokkaido’s light, high-quality powder snow, March is your last chance before the next winter season. After that, temperatures begin to rise gradually, though conditions remain cold compared with many other Asian destinations. For a more spring-like atmosphere, late April or later is a better choice, with a thick, adjustable outer layer still recommended.

A special note for those traveling with seniors, children, or anyone sensitive to temperature changes. Spring often brings large temperature gaps between morning and evening, which can cause headaches or general discomfort. Bringing regular medication is advised for peace of mind during your trip.

While spring is already starting to show across much of Japan in March and heavy snow has largely disappeared on the main island, travelers hoping to ski in Japan should not give up just yet. Hokkaido still has plenty of snow at this time of year, making March your final chance of the season to enjoy skiing here. It is also a quieter period, as it falls outside the peak ski season, meaning fewer crowds on the slopes.

That said, recent years have seen warmer temperatures overall, and snow conditions in Hokkaido in March can be firmer than midwinter. Consider fresh powder a bonus rather than a guarantee, and plan with that mindset in mind. For those flexible with expectations, March remains a rewarding time to enjoy Hokkaido’s ski resorts with a more relaxed atmosphere.

Hokkaido begins to warm up gradually in April, with average temperatures reaching around 10°C (50°F) and average daytime highs climbing to about 15°C (59°F). You can finally start to feel hints of spring, but it is still important not to let your guard down. Early mornings and evenings often drop below 10°C (50°F), and daily temperature differences of around 10°C (18°F) are common. These sharp swings can lead to fatigue or discomfort, so layered clothing is strongly recommended. Adjusting layers throughout the day helps maintain comfort, and bringing any regularly used medication is wise in case temperature changes affect your condition.

Although April temperatures in Hokkaido are much milder compared with winter, travelers from Asia may still find it cold, while it is generally comparable in temperature to Europe and North America around the same timing. Preparing winter-weight clothing or a warm outer layer is still the safest choice for staying comfortable.

Beyond its famous powder snow, Hokkaido’s dramatic natural landscapes are a major highlight in their own right. Iconic sights such as Mt. Yotei, often called “Ezo Fuji (Mt. Fuji of the North),” and Noboribetsu Hell Valley, where steam rises from the ground to create an almost otherworldly scene, are must-see destinations. Visiting these places in person offers a powerful reminder of Hokkaido’s raw natural beauty and adds a memorable chapter to any trip.

As the weather becomes more comfortable in April, it is a great time to explore outdoor scenery and, if timing allows, enjoy cherry blossoms as well. Sakura season arrives later in Hokkaido, so travelers hoping to see cherry blossoms in April should focus on southern Hokkaido, including areas such as Hakodate, from mid to late April. Planning your itinerary around this timing gives you the best chance to catch Hokkaido’s late-blooming sakura.

In May, average temperatures in Hokkaido approach 15°C (59°F), with average daytime highs nearing 20°C (68°F). It can feel a little chilly when the wind picks up, but on sunny days the weather is generally comfortable and pleasant. This period also marks peak flower season across the region, with plum blossoms, cherry blossoms, and tulips blooming one after another. Hokkaido feels fully alive with spring energy, making it an excellent option for travelers who missed flower season on Japan’s main island and want one last chance to enjoy seasonal blooms.

Although daytime conditions are mild, nighttime temperatures in May can still drop to around 10°C (50°F). The difference between day and night remains noticeable, so carrying a light jacket is recommended to stay comfortable in the early morning and evening hours.

May brings warm, stable weather to Hokkaido, making it an ideal time for relaxed sightseeing and enjoying the region’s natural scenery. One must-see spot is the famous cobalt-blue artificial pond, Shirogane Blue Pond (Aoike). From May to June, when the weather is settled and skies are clear, the pond is at its most striking. The unreal blue water paired with straight white birch trees creates a scene that feels almost dreamlike. If you are visiting Hokkaido in May, this is a view well worth seeing in person.

With warmer temperatures, cherry blossoms continue to bloom across different areas, making it a great time to explore parks and natural landscapes. Strolling outdoors and soaking in the gentle spring atmosphere of Japan’s northern island is one of the simple pleasures of traveling in Hokkaido at this time of year.

Spring weather in Hokkaido varies clearly by month. March still holds onto winter-like cold, April is known for large temperature swings between day and night, and May finally turns warm and stable, with flowers beginning to bloom across the region. Choosing the right month depends on what kind of scenery and activities you are looking for.

A: If you enjoy winter outdoor activities, some ski resorts with longer seasons allow you to ski well into spring. Travelers hoping to see snowy landscapes should aim for March. Those interested in spring river rafting after the snow starts to melt may prefer April, while visitors who want a true spring atmosphere with flowers and greenery should plan their trip for May.

On Japan’s main island, snow usually starts melting by March. In Hokkaido, however, snowfall often continues through March, making it the final chance of the season to experience snow before winter returns at the end of the year.

Aside from snowfall in March, spring weather in Hokkaido is generally stable in April and May, with relatively little rain or snow. This makes it a comfortable season for sightseeing. Bringing a lightweight folding umbrella is still a good idea, reminding yourself just in case.

As Japan’s northernmost region, Hokkaido always seems to welcome the seasons a little later. While snow begins to melt on the main island in March, Hokkaido can still be covered in soft white powder. And when much of Japan is already lush and green in May, Hokkaido is just beginning to bloom with delicate pink flowers. This delayed arrival of spring gives the region a charm that feels distinctly its own.

One important reminder is that late April to early May coincides with Golden Week, one of Japan’s major holiday periods. During this time, some shops may close, reservations may be limited, and popular spots can become crowded. Planning ahead is essential to avoid unexpected disruptions to your trip.
